To all 'whom t may concern:

Be it known that Yiinnrniir E. Knoncnn, a

citizen of the United States, residiinig` at lliiilwaulree, in the county of Milwaukee and State of W'isconsin, has invented ay certain new and useful Valve, of which the follow ing is a specification. Y.

This invention relates in general to iinprovements in the-art of controlling the flow` of vfluids, and relates more specifically to improvements in the const 1uction and operation lof valve mechanisms and espe` cally` `flush valve. structures for `water closets, urinals and the like.V

An object of the invention is to provide a valve which is extremely simple and com-V pact in construction and efficient in operation. Y Some of the more important specific objects of the' `present invention are as followsz- To produce a manually controllable flush valve which is especially adapted for iii` stallation in private dwellings of moderate value.

To providea toilet flushing deviceV which is extremely simple and rugged in con-' wliich-perfoms its function effectively and which is noiseless inoperation..`

To provide a flush valve which is absolute-A ly fool proof and which may be installed in connection with existing toilets.` i

To provide a valve mechanism all parts ofwhich are conveniently accessible for in-` spection and cleaninsg,y vand which may be readily maintained in sanitary and oper- -ative condition.

To provide a manually controlled valve structure which is operable automatically by fluid under pressure and in `which the closing' head for` an end of the casing` 2, a

use of springs is eliminated'.

To provide. flushing" mechanism lfor .-watei".

in thecasing 12, a servo motor 2O for operatclosets and the like, in which leakage and waste Vof wateris avoided,'and in which undesirable sweating" of liquid Vcontainers is eliminated.4

To provide other improvenientsin the ldetails of construction and lll the operation of flushing devices and valve structures in general, whereby the eliiciency of such devices is enhanced and the cost oflconstruction and maintainance thereof is reduced to a minimum.

These and other objects and advantages of` the present invention will be apparent in the course of the following description.

A clear conception of an embodiment of the invention and of the manner of manipulating and operating devices constructed in accordance therewith, maybe had by referring' to the drawing accompanying' and forming a part of `this specication in which like reference characters designate the same or similar parts in the various views.

The improved flush valve structure coinf prisesinv general a main valve casing; 2, a

main sleeve valve 4L reciprocable within a` bore of the casing 2, `an auxiliary valve casing 12 secured to and forming an enfluid distributing valve 14 rotatable withingthe distributing` valve 1 41, and reciprocabl'econtrol valve 13 slidable within a bore of the casing 12. While the main Vvalve irai ans'rares rA'reNr ortica.

as well as the other structure may be disposed otherwise than as illustrated without departing from the present invention. The main valve casing 2 is provided with a main Huid or water supply 3 extending transversely of the direction of movement of the valve 4, and with a main fluid or water discharge 5 communicating with the interior of the valve 4 in the direction of movement thereof. A removable valve seat 6 is clamped between the casing 2 and the discharge 5, and provides a seating for the valve 4 when closed. The main valve 4 is formed as a sleeve the exterior of which snugly lits a bore of the casing 2 and the interior of which is bored to snugly lit the stationary partition 7. The partition 7 is stationarily supported from the auxiliary valve casing 12 by means of a rod like or tubular member 8. The upper end of the sleeve valve 4 is provided with an inwardly extending flange or end head 9 having a central bore which snugly lits and is slidable along the member 8. The head 9 is movable from the partition 7 to the auxiliary valve casing 12 during opening movement of the main valve 4. l

The fluid distributing valve 14 is of the tapered rotary plug type and is mounted in a tapered bore in the casing 12, to rotate about an axis which intersects the central axis of the main valve 4. The larger end of the tapered valve 14 is provided with an actuating arm or lever 17 the upper end ot which is biturcated and engages a pin 13 projecting laterally from the servo motor piston rod 19. The valve 14 is normally retained within the tapered bore of the casing 12 by means of a leaf spring 21 carried by the cover plate 22, the valve 14 being readily removable upon removal of the plate 22 and spring 21. The valve 14 has a pair ol straight through openings or passages 23, 29 which penetrate the valve 14 at different angles, and is also provided with an irregular peripheral port 27, see Fig. 7. These passages and ports are adapted to communicate with passages 26, 10, 1 1, the two latter of which extend through the tubular inember 3. The passage 10 terminates in the space below the partition 7 while the passage 11 terminates laterally in the space between the valve head 9 and the partition 7. The passage 26 terminates in the space between the valve head 9 and the auxiliary valve casing 12. y

The fluid pressure actuatedservo motor 2O comprises a. piston 16 reciprocable horizontally within a bore ot' the casing 12, and' a piston rod 19 secured to the piston and connected to the valve 14 by means of the pin 13 and lever 17. The manually movable servo motor control valve 13 is vertically slidable within a bere out the casing 12 by means of an actuating lever 15 having a projection 30 fitting a slot in the upper end of the valve 13. This coaction between the lever 15 and the valve 13 prevents rotation of the valve. The lever 15 is pivotally supported by the casing 12 which provides a limit stop 31 l'or the lever. The valve 13 is provided with independent ports or passages 35, 36, the Yformer of which extends both longitudinally and transversely within the valve 13 and the latter of which extends transversely directly therethrough. The servo motor control ports 33, 34 extend through the casing 12 from opposite sides of the piston 16 to the control valve 13. A port 37 extends through the casing 12 from the valve 13 to the exhaust port 10. The casing 12 is also provided with an actuating tluid supply chamber 23 from which fluid distributing ports 24, 25 extend through the casing 12 to the plug'valve 14, while a port 32 extends 'from the chamber 23 through the casing 12 to the control valve 13. The control valve 13 is formed'ot suliicient length so that when the valve is moved downwardly as shown in Figs. 1 and 4, the lower extremity ot the valve 13 depends into the chamber or space between the valve head 9 and the casing 12.

During normal operation of the improved valve mechanism, and assuming it to be desirable to open the valve 4 as when it is desired to flush a toilet or a urnal, it is necessary only to depress the lever 15 to move the valve 13 from the position indicated in Fig. 5 to the position indicated in Fig. 4. When the valve 13 is thus moved, the space to the left of the servo motor piston 16 is thro-wn into communication with the exhaust passage 10 through the ports 33, 35, 37 and the space to the right ot the piston 16 is simultaneously brought into communication with the Huid supply chamber 23 through the ports 34, 36, 32, as shown in Fig. 4. Fluid under pressure is then admitted through the ports 32, 36, 34 to the right ot the piston 16 causing the piston and the rod 19 to move rapidly toward the left as viewed in Fig. 4 and to position the distributing valve 14 as shown in Figs. 2, 3 and 4. lith the valve 14 thus positioned, the through port 23 establishes direct communication between the pressure supply chamber 23 and the space between the valve head 9 and partition 7, through the ports 24, 23, 11. rlhe peripheral port 27 of the distributing valve 14 simultaneously connects the space above the valve head 9 with exhaust through the ports 26, 27, 10 thereby permitting the gradual accumulation of Huid under pressure below the valve head 9 through the ports 24, 23, 11, to sloPwly raise and open the main valve 4, see Fig. 1. As the main valve 4 reaches the upper limit of its travel, the moving end head 9 directly enga-ges the depresssed lower end of the control valve 13 lll) as indicated in Fig. 3, and `automatically returned to its upper or normal position, the space to the right of the'servo mortor piston` 16 is automatically connected with exhaust through the `ports 34, 85, 37, 10, while the space to the left of the piston 1G is simultaneously connected with the fluid pressure supply 23 through the ports 32, 36, 33, see Fig. 5. The servo motor piston 16 then `moves rapidly toward the right as tribnting valve 14 as shown in Figs. 5 and 6. Wit-h the valve 14 thus positioned, the through port 29 establishes direct communication between the pressure supply chamber 23 and the space above the valve head 9 through the ports 25, 29, 26. The peripheral port 27 of the distributing valve 14 simultaneously `connects the space between the valve head 9 and the partition 7 with exhaust by connecting the port 11 with the exhaust port 10, thereby permitting the gradual accumulation of fluid under pressure above the valve head 9 to slowly lower and Vclosethe main valve 4. When the main valve 4 has been fully closed, the various valves and levers are in position for subsequent o-pening thereof by merely depressing the lever 15.` i

It will be `obvious that the quantity of water permitted to flow from the supply 3 to the discharge 5 during one operation of the main valve 4 is readily controllable by varying the cross-sectional areas lof the fluid supply and discharge ports. For ports of predetermined area Vand with constant pressure in the supply 8, the quantity of fluid passing the main valve 4 during opening and closing thereof will valways be constant. The apparatus has been found' especially applicable as a toilet and uriiial flushing device which may be readily substituted.

lfor the cumbersome flush tanks now universally used. The structure is extremely simple, rugged and inexpensive in construction and may be manufactured and installed at relatively moderate cost. When installed in private bath rooms, the mechanism may be readily concealed in the wall to leave only the lever 15 projectiiio'. The `apparatus is moreover practically noiseless in operation and the various valves are conveniently accessible and removable. In constructing the mechanism, the various parts slilould be properly fitted and packed to avoid leakage. and to maintain operation at maximum efficiency. i

`While the mechanism has been described more or less in detail and with the aid of specific terms, it should be understood that it is not desired to limit the invention tothe exact details of construction and of operation herein shown and described for various modifications within the scope of the claims may occur Vto persons skilled in the art.
